I am interested to see the transformation (not just in clothing, weapons, armour but also psychologically) of Thorin (and the other dwarves) from the "homeless" dwarves of the beginning of The Hobbit to the dwarves who have reclaimed their kingdom under the mountain.

I would expect them to be more armoured, etc (similar to Gimli from LOTR) at the end of the story. But I look forward to the more "plain clothes" dwarves at the beginning of the story.
